Sullivan, who was credited with developing second-year receiver Cecil Shorts and rookie receiver Justin Blackmon, came out of retirement to coach for the Jaguars. He will be entering his second year with the team.

Blackmon, the Jaguars’ first-round pick, and Shorts, a second-year player who didn’t play much as a rookie, combined for 119 catches, 1,700 yards receiving and 12 touchdowns.

“I had a good visit with Gus, and I’m appreciative of the opportunity to move this thing forward and build a program,” Sullivan said. “It’s going to be a nice opportunity to work with Cecil and Justin again and keep working to get better at what we do.”

Sullivan was impressed with Bradley after meeting with him.

“You knew Gus was a good leader when you watched Seattle play defense and how he interacted with them,” Sullivan said. “He’s worked hard to get to where he is, and he knows the work ethic it takes to be good in this league.”

Sullivan is the first offensive staff member to join coordinator Jedd Fisch’s side of the football.

Duffner will be entering his eighth year with the Jaguars and will work for his third head coach. Minus projected starters Daryl Smith and Clint Session, Duffner helped Paul Posluszny and Russell Allen have career years in 2012 and also coached Julian Stanford into a starting role.

“I got an opportunity to visit with Dave Caldwell and Gus Bradley and when I did, I was really excited with what I saw and heard from both of them,” Duffner said after watching the North team practice at Ladd-Peebles Stadium. “I’m anxious to get back to work.”

Unlike last year, when coordinator Mel Tucker was retained by Mularkey, Duffner will have to learn the new system and philosophy that will be implemented by new coordinator Bob Babich.

“Football is football,” Duffner said.

Duffner was brought to the Jaguars by former coach Jack Del Rio. Jacksonville is the second-longest stay of his 38-year coaching career — he spent 11 years as an assistant and then head coach at Holy Cross (1981-91). He came to the Jaguars after NFL stints with Cincinnati and Green Bay.

“I’ve always enjoyed the loved the fans in Jacksonville,” Duffner said. “Based on that and [Caldwell and Bradley] and what I’ve learned from them, I’m excited about getting going.”

Wow I thought the Jags led the world in dropped passes last year, for much of the year these same Jags fans were harping on JB for poor route running, drops and lack of focus and now more of the same. Our linebackers couldn't cover or tackle in space and I know of at least 10 in your hands interceptions that were dropped by this "elite" lol linebacker core. So if these two hires are indicative of the new HC and GM the Jags are in a world of trouble again.

Yet another decision by the Jags that I am happy with. Jerry Sullivan is one of the best WR coaches in the NFL and look at what he did with Shorts and Blackmon last year (with Gabbert & Henne as QBs no less). Give him a few more years and some more rookies from the draft and we may have one of the best WR units in the NFL.

Mark Duffner is a very good LB coach. Honestly LB has always been the best part of our Defense (except the years with Stroud & Henderson) and Duffner was the coach all of those years. With Poz & Allen and hopefully some new guys coming in, we should be good at LB.

Regarding QB, if I was the GM for the Jags I would have to look at getting a free agent QB in here for a few years along with the best possible QB coach possible. I'd cut Henne and have Gabbert ride the bench and see if he's salvageable--if not next year cut him. Meanwhile every year pick a QB in the draft. It's STUPID to only have two QBs on your roster and yet have a bunch of special team only guys. Look at the Patriots taking a chance on Mallet and letting him grow--when he is ready they can either trade him for draft picks or he can replace Brady. If he had busted, then they cut him and move on---unlike the Jags who went years without drafting a QB.

I have to say this new "regime" is making what appear to be all smart decisions. That said, it can all be for nothing if you don't assemble at the QB position. Get a caretaker like Alex Smith in here and draft another prospect (to compete with Gabbert) for down the road. Hoping to catch lightening in a bottle with a Kapernick is fantastic bit it's too much to "count" on. Have a solid plan and build on it. So far so good.

@truthteller12 I don't disagree with you, I'm just wondering from what magical tree everyone is expecting this quarterback to fall from. Just because the new GM says that he'll bring in competition at qb(via free agency, trade, or the draft) doesn't guarantee that there will be a new starter under center, much less a significant upgrade. I could be wrong, but don't be too disappointed if we roll with Gabbert or Henne next year.
